We should add this condition for all the MySQL config, only with this change, the rest of the MySQL components will be deployed but without the PVC it will eventually fail.

Also, while testing set managedDatabase.enabled: true in the development branch, and create a public managed MySQL server for testing purpose and use its credential to test it.

badgr-server/chart/values.yaml

Lines 31 to 36 in a4df1c5

	managedDatabase:
	enabled: false
	host: dummyval
	user: dummyval
	name: dummyval
	password: dummyval

I also see there are a lot of MySQL config files here, which are created long back, it is a good opportunity to refactor this.

Can you remove all the MySQL config files and use the Bitnami MySQL chart and update the badger's deployment configs accordingly?

you can refer to this implementation - https://github.com/WHOAcademy/learning-delivery-api/blob/main/chart/Chart.yaml#L25-L29
